Headers

Authorization

string

Optional API key: Bearer vulcx_.... Anonymous calls are allowed but capped at a small per-IP rate limit — see Rate limits.

Example:

"Bearer vulcx_..."

Body

application/json

Parameters for building the route instruction as a CPI target. Like InstructionsRequest, but the signer is a calling program's PDA (the on-chain authority that will invoke_signed into route) rather than a wallet.

authority

string

required

The calling program's PDA authority — owns the token accounts and signs the swap via invoke_signed inside the integrating program.

Example:

"EJxE7RDaP5pmoVzzHRb4fufCNq3wsCgdUbJ8PCXHZNUP"

inputMint

string

required

Example:

"So11111111111111111111111111111111111111112"

outputMint

string

required

Example:

"uSd2czE61Evaf76RNbq4KPpXnkiL3irdzgLFUMe3NoG"

amount

string

required

Amount in the smallest token units.

Example:

"1000000000"

swapMode

enum<string>

required

Available options:

ExactIn,

ExactOut

Example:

"ExactIn"

slippageBps

integer

default:50

Example:

50

allowedIntermediateMints

string[]

Route corridor: multi-hop routes may only pass through these mints, closing the requiredTokenAccounts set over ATAs you pre-provisioned. Input and output mints are implicitly allowed. Empty/omitted = unrestricted.

Maximum array length: 16

Example:

[
  "So11111111111111111111111111111111111111112"
]

maxHops

integer

Cap on route length (1 = direct pools only). 0/omitted = server default.

Example:

2

excludeDexes

enum<string>[]

DEX types to exclude from routing. Excluding "moonit" also lifts the authority-writable requirement on the CPI.

Available options:

vortex,

fluxbeam,

moonit

Example:

["moonit"]

referrer

string

Optional referrer wallet (base58). Receives integratorFeeBps in full, paid on-chain in the output token in the same transaction as the swap. Required whenever integratorFeeBps is set.

Example:

"EJxE7RDaP5pmoVzzHRb4fufCNq3wsCgdUbJ8PCXHZNUP"

integratorFeeBps

integer

Your own fee rate in basis points of the output, kept by you in full. Requires referrer — a rate with no wallet to pay it to returns 400. Added to platformFeeBps, not carved out of it; the sum may not exceed 100 bps.

Required range: 0 <= x <= 100

Example:

20

Response

Route CPI account list built successfully.

success

boolean
